I haven't had to put any new knocks on them but I was told that the knocks for some of the easton arrows are the same size. If you take an arrow to an archery shop I'm sure they can find one that will fit. If you do find out exactly what knock fits, please let me know also. I like to keep some extras on hand. Its not a problem with the questions.Its a tough decision to make a switch to something like new arrows when something is working already.
